Hi A,
It is a WTSUG group but many attend are Non-TS Users also. I have many friends who use Ninja, MultiCharts, NeoTicker etc.. who attend this meeting.
Main focus in my view is TA and software tools etc. They have excellent presenters from time-time and the guy who organizes is brilliant (Bruce).
Mostly traders but some solid developers with varied backgrounds attend this meeting. The group size also varies from topic to topic, presenter, weather etc. But you can attend free few meetings and if interested the membership fee is like $20 a YEAR. I have not attended SMT for quite a while, but it may be more designed for investors, I think. You can also attend SMT meetings (few) for Free.
Regards,
Suri
